RIBBON-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 623,900, dated April 25, 1899. Application filed December 17, 1898- Serial No. 699,592. (No model.)

To ctl whom it ntcty concern:

Be it known that we,SoLoMoN GoTrsoHALL, of the city of New York, borough of Manhattan, in the county of New York, and HENRY KAMSLER, of the city of New York, borough of Brooklyn, in the county of Kings, State of New York, have invented a new and Improved Ribbon-Cutting Machine, of which the following is a full, clear, and exact description.

Our invention relates to an improved machine designed for cutting cloth into ribbons, and comprises a novel form of knife for cutting the cloth and means by which said knife is supported and adjusted.

Our invention further comprises novel features of construction hereinafter described and claimed.

Referenceis to be had to the accompanying drawings, forming a part of the specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a top plan view of our machine.

Fig. 2 is a side elevation of the working parts thereof, and Fig. 3 is a detail showing one of the knives separately. Our device is intended particularly for us in connection with the manufacture of ribbons, in which process the ribbons are Woven as a wide strip or web of cloth, havingthe warps at the points where the cloth is to be cut slightly separated, so that it may be out upon these lines, and thus form a number of ribbons. This results in much cheapening the manufacture of ribbon, as it is much easier and less expensive to weave a series of ribbons in one web than to weave the same amount of ribbon each as a separate web.

Our device is mounted upon a suitable frame A and comprises, essentially, two rollers B and 0, one for supplying the web and the other for rolling it up, in connection with suitable cutting-knives H and smoothing-bars E and E.

The rollerB is the one upon which the web is wound during the process of cutting. This is connected by means of a suitable train of gears J with a tight and loose pulley J, upon which the power-transmitting belt runs.

The cloth is placed within the machine by winding it upon rollers O and placing these rollers one at a time within journals formed in the framework. The bearings for these rollers are shown in Fig. 2, and consist of a lower block G, having a recess adapted to receive the journal and an upper block G, having a similar recess, said blocks being pivoted at 9, so that the upperblock may be readily raised for inserting and removing the rollers. The upper block G is held down upon the journal by means of a threaded rod or shaft g, which passes through the upper block G and screws into the lower block. By this means friction may be placed upon the journal, so as to retard the web as necessary.

The web D as it leaves the roller 0 passes over a smoothing-bar E, which extends entirely across the machine, and beneath a second smoothing -bar E of a similar form. These bars are mounted upon blocks e and e, which are adjustable vertically upon posts F, located one on each side of the machine, so that the relative elevation of the two bars E and E may be adjusted as desired.

One end of the roller B,upon which the web is wound, is journaled in a block I. This block is mounted upon the frame so as to slide within a slot 1. The block I is moved toward and from the opposite roller by means of a threaded rod 1 which passes through the block I and has a thrust-bearing in a lug or standard I upon the frame. By adjusting one end of the roller B toward and from the roller 0 the tension upon the web may be adjusted so as to secure a true and accurate winding of the web upon the roller. An ad justment of this sort is often necessary,as the warp of the opposite sides of a web is not always stretched the same amount.

The knife is shown in detail in Fig. 3 and consists of a rod H, which is provided at each end with hooks h and h. The hook his simply a lateral projection substantially at right angles to the body of the rod. The inner edge of this hook h, as well as the bend and a small portion of the adjacent bod y,is sharpened to a knife-edge and acts upon the goods to cut it. The opposite hook h is adapted to hook over the rod K, which extends across the machine at one side. This rod is supported upon blocks 6 which may be vertically adjusted upon standards F.

The rod K is provided with a series of IOC ' held in place.

grooves or notches spaced at a short distance from each other and extending throughout its entire length. The hooks h of the cutting-rods are adapted to enter these notches,and thus be They are rapidly shifted from one notch to another, and thus adjusted for cutting the web into ribbons of any width desired. By thus forming the knives upon one end of rods of considerable length and supporting them by the opposite end only, so as to leave the cutting end free to swing laterally, the knife will follow the threads of the,

web with great accuracy, even if the position of the cuttingpoint should shift laterally of the machine a considerable amount. It is thus possible to cut the web into strips of any Width desired. The adjustment of the knife to this end need not be exact, but approximate and such as will permit it to swing sidewise a limited degree, as may be desired.

The cutting-hook hof the knife extendsjust within the smoothing-barE. The two smoothing-bars E and E are so adjusted relative to each other and the position of the roller from which the web is wound that the web is slightly deflected, so as to cause the web to press upon the bar E, and thus be smoothed out.

This construction of machine makes it possible to accurately cut goods of this character and to do the same rapidly, thus making the manufacture of ribbons much cheaper than heretofore when woven in separate webs.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A cloth-cutting machine comprising two rollers and means for rotating them to transfer the cloth from one to the other,a friction device or brake for the supplying-roller, a series of knife-rods having side-extending knives at one end engaging the cloth and extending in the general direction of the travel of the cloth at the cutting-point, and a support for the other end of the knife-rods, substantially as described.

2. A cloth-cutting machine comprising two rollers and means for rotating them to transfer the cloth from one to the other, means for adjusting the angular position of one roller toward and from the other, a series of kniferods having side-extending knives at one end engaging the cloth, said rods extending in the general direction of travel of the cloth at the cutting-point, and a support for the other end of the knife-rods, substantially as described.

3. A cloth-cutting machine comprising two rollers, and means for rotating them to transfer the cloth from one to the other, a hinged cap for the journals of the supplying-roller, a threaded rod for holding it down, a series of knife-rods having side-extending knives at one end engaging the cloth, said rods extending in the general direction of travel of the cloth at the cutting-point, and a support for the other end of the knife-rods, substantially as described.

4. A clothcutting machine, comprising means for moving the cloth, two adjacent smoothing-bars engaging the cloth to deflect it in opposite directions, one of said bars forming a support for the knife ends of the kniferods, a series of'knife-rods having a hook formed on one end and sharpened to form a knife which engages the cloth between the two smoothing-bars, and a support for the other end of the knife-rods permitting them to swing transversely the cloth, substantially as described.

5. A clothcutting machine, comprising means for moving the cloth, two adjacent smoothing-bars engaging the cloth and deflecting itin opposite directions, a series of knife-rods having hooks formed at each end one end being sharpened to form a knife, said end resting upon one of the smoothing-bars and the knives engaging the cloth between the two smoothing-bars, and a notched or grooved bar adapted to receive the hooks upon the opposite end of the knife-rods and permitting a transverse swinging movement of the knives, substantially as described.
